Ignore case

The problem is that you are iterating through the characters of the lowercase version of your original, uncertainly cased string, and then checking how many times each of these lowercase characters appear on that original string. It's easy to see where this goes wrong.

Adding this to the beginning of your function should fix it:

word = word.lower()

You can print to input to the console.

I trying the duplicate_encode kata for Python.

Despite all test are ok, when trying the final attemp it gives me an error in the last test, it returns:

 '))(()())())' should equal '()(((())())'

My code is:

 def duplicate_encode(word):
   nword=''
   for c in word.lower():nword+='(' if word.count(c)==1 else ')' 
   return nword

I do not have feedback of the input that gives error. Can someone help me please?

Thanks.
